Abstract

See full text

A digital camera includes a focusing-control-unit that calculates a defocus amount using detection signals of phase difference detection pixels and drives a focus lens according to the defocus amount, and a movement-detection-unit that detects whether a movement is present in a captured subject-image. The focusing-control-unit calculates the defocus amount according to an auto-focus instruction, and drives, in a case where the defocus amount exceeds a threshold-value, the focus lens according to the defocus amount and then performs the phase difference AF again to complete auto-focusing. Further, in a case where the defocus amount is equal to or smaller than the threshold-value, the focusing control unit performs the phase difference AF only once to complete the auto-focusing. Further, in a case where a movement is present in the subject-image, the focusing-control-unit sets the threshold to a larger value than in a case where a movement is not present in the subject-image.
